VAGINAL SYRI'NGE.

Specification of Letters Patent.

Patented July 5, 1910.

Application filed October 5, 1909. Serial No. 521,112.

To all whom it may concern:

'Be it known that I, IDA L. STEVENS, a citizen of the United States, anda resident of St. Louis, in the State of Missouri, have invented a newand Improved Vaginal Syringe, of which the following is a full, clear,and exact description.

The purpose of my invention is, to provide a vaginal syringe embodyingnovel details of construction, which adapt the instru ment for veryconvenient service, facilitate the introduction of medicament in eitherliquid or powdered form, prevent an improper escape of liquid while inuse, render the instrument extremely simple, enable the quick and easyseparation of parts to permit their renovation, and provide a sanitarydevice at moderate cost.

The invention consists in the novel construction and combination ofparts, as is hereinafter described, and defined in the appended claims.

Reference is to be had to the accompanying drawing and referencecharacters thereon, the view shown being a sectional side elevation ofthe improved vaginal syringe.

In the view shown, A represents a bulbous receptacle of suitabledimensions, having a fiat bottom wall A of sufficient area to adapt thereceptacle for seating on a level support. Upon the upper portion of thebody A a neck A of reduced diameter is formed, said neck at its free endterminating in a bead a that is rounded exteriorly and projects from theouter surface of the neck. The body A and neck A are formed ofvulcanized rubber having proper elasticity to permit its manualcompression.

A preferably cylindrical barrel, formed in two sections B, O, isprovided, the section B, of greatest length, having an interior thread 5formed in its lower end, wherein an exterior thread 7) on the upper endof the sec tion C is adapted for screwed insertion, the true edge on thelower end of the section B seating liquid tight upon a radial flange Cthat projects from the upper edge of the lower section G1 On the lowerend of the lower barrel section 0, a transverse wall C is formed, havinga convex outer surface 0, and from said wall a circumferential rib 0projects, that is rounded exteriorly.

In the neck A opposite the bead a there on, a groove 0 is formed,wherein the rib 0 may be readily introduced, and be therein held liquidtight, due to the construction of the neck, thereupon, the convexsurface 0, facilitating the introduction of the rib 0, within the groove0 The end wall C is numerously perforated as shown at 6, these smallperforations permitting the free passage of liquid from the receptacle Atherethrough.

Upon the exterior of the upper section B, a circumferential flange B isformed or secured, at a suitable distance from the upper end thereof,said flange having concavo-convex form and a circular edge, the concaveside thereof beinglowermost. The upper end of the barrel section B ismainly closed by a transverse wall d, wherein numerous fine perforationse are formed, and, as shown, the exterior surface of said end wall isrendered convex.

It will be seen that any suitable liquid wash or medicinal preparationmay be readily introduced within the receptacle A, by compressing it soas to expel a portion of the contained air therefrom, and while socompressed introduce the nozzle end of the barrel section B, into theliquid, whereupon a relaxation of pressure on the bulbous receptaclewill permit it to resume its normal shape and cause suction, that willeffect the inflow of the liquid into the receptacle.

In use, the nozzle end having the perforated wall cl thereon isintroduced within the vagina, after the instrument has received a chargeof liquid wash, the flange B by pressure thereof against the bodysealing the opening so as to prevent any escape of the liquidexteriorly. Obviously if pressure is applied upon the bulbous receptacleA, the liquid therein will be copiously sprayed from the nozzle end ofthe instrument into the vagina, thus thoroughly cleaning the same. Nowupon relaxing pressure on the receptacle A, it will expand and assumenormal shape,thus creating a partial vacuum therein, which will draw theliquid into said receptacle, and the instrument may be removed from theperson.

By contracting the bulb A, and allowing it to expand successively, whilethe nozzle end of the barrel section B is immersed in a vesselcontaining soapy water or other detergent liquid, the instrument may bereadily cleansed; or, if preferred, the barrel sections may be detachedfrom each other and the receptacle A removed from the section C,

' thus permitting each member to bequickly for their renovation.

washed inside and outside in a proper liquid If the medicament to beapplied Within the vagina is in powdered form, the instrument is driedthoroughly, and a proper quantity of the powdered'medicinal preparationis introduced'within the lower section C of the barrel, by removing theupper portion B therefrom, this insertion of the powder being effectedwhile the bulbous'receptacle A is in normal expanded condition. Uponreplacing the upper section ,B of the barrel, the instrument may now beintroduced within the part tobe treated, and

upon collapsing the receptacle A the powder willbe blown from thebarrel, andcoat the tissue it is to heal. 7

It is'to beunderstood that the barrel in complete form is made of rigidnon-porous material, which may be metal, but referably is hard rubbercompound highy p01:

as new, and desire to secure by Letters Patent: V

1; In an instrument of the character'described, the cylindrical barrelformed in two sections, a threaded connection between meeting ends ofsaid sections, end walls on the sections having convex outer surfacesand numerous perforations therein, and a concavo convex circumferentialflange forimed on one section near its perforated en c 2. Thecombination with an elastic bulbous receptacle, having a contractedneck, a circumferential bead on the free end of said neck, and alsohaving an inner bottom groove thereon opposite thebead, of a cylindricalbarrel formed in two sections, a threaded connection between the meetingends of said sections, a radial flange on the end of one section onwhich theend of the other section has contact, outer end walls on saidsections having convex outer surfaces and numerous perforations in eachend wall, and a circumferential bead on one end wall that engageswitlhin the groove in the neck of thereceptac e.

In testimony whereof I "have signed my name to this specification in thepresence of two subscribing witnesses.
